It’s alive! Dynamic components in Angular
summary
Runtime selection of actual component instances replaces huge ngSwitch templates by resolving factories with ComponentFactoryResolver or directly inserting via ViewContainerRef.createComponent, and lazy-loading separate lazy-loaded NgModule bundles so only needed component code ships. Demo shows dynamically added widgets with working change detection, reachable inputs and output subscriptions; notes lifecycle caveat (ngOnChanges not auto-run for raw instance members). Also mentions Angular Elements and upcoming Ivy as alternative simplifications.
